Description
Technical field
The present invention relates to paint field, more particularly to a kind of electrostatic screen graphene anticorrosive paint and preparation method thereof.
Background technology
Static discharge is a kind of phenomenon in daily life and its common, and in a dry environment, human body is contacting sometimes
It can feel there is electricity during metal object, also can be appreciated that electric spark once in a while, here it is static discharge phenomenons, that is, ESD event.Due to
Phase mutual friction between object, easily generates electrostatic accumulation, occurs electrostatic hazard, interference electronic computer, precision instrument it is normal
Work, can also trigger explosion and fire when serious.Static discharge can generate of short duration discharge current and very strong electric discharge magnetic field.It can
The electronic equipment malfunction or even internal component for causing operation are damaged, and cause equipment loss of function.
High molecular material is the material being made of the higher compound of relative molecular mass, including rubber, plastics, fiber,
Coating, adhesive and polymer-based composite etc..Most of high molecular material based on high-molecular compound is all exhausted
Edge body, but charge can be also carried under the action of electrostatic.The accumulation of static electricity on the non-metal items such as high molecular material surface reaches one
Determining degree will discharge, and various precision instruments, precise electronic component is caused to puncture and scrap or even inflammable and explosive substances is caused to rise
Fire or explosion, cause huge Loss of Life and property.In addition, be accumulated in the electrostatic of surface of plastic products since dust suction is serious and
It is difficult to purify, so as to the appearance for influencing plastic products and in super-clean environment (such as operating room, computer room, precision instrument etc.)
Using.Polymer surface has electrostatic in order to prevent, and there are two types of methods for the prior art to handle：One kind is outer spreading type, one
Kind is inner additive type.Outer spreading type is then quiet to prevent or accumulate in frosting one coating film of formation using anti-static coatings
Electricity.For old war profit et al. using acrylic resin as base-material, the surface resistivity of coating can be made by adding in some electrically conductive materials such as graphite etc.
For 106 ~ 9 ohm-sqs centimetre.But the most adhesive force of coating and oil resistivity obtained by the method for this addition conductive material
Difference, and cost is higher.It, can also be in the direct applying conductive of frosting since some electrically-conducting paints can be used for antistatic
Coating forms antistatic backing to play the role of antistatic, such as conductive polyaniline composite nano-coating can direct spraying or brush
It is coated on plastic basis material.But the operability of this kind of material is bad, it is difficult to process.
The Chinese patent of Application No. CN201410396314.8 disclose a kind of high hydrophobic type antistatic composite coating and
Graphite powder and sodium nitrate are added in the concentrated sulfuric acid in this application, potassium permanganate are added in after ice bath stirring, slowly by its preparation method
Distilled water is added dropwise, removes excessive potassium permanganate afterwards, filters off sulfate ion and obtains graphite oxide, be added to organic solvent
In, supersound process prepares graphene oxide solution；Sequentially added into graphene oxide solution isocyanic acid, long-chain modifier,
Reducing agent is chemically modified graphene oxide, washs drying, obtains modified graphene；Using resin as matrix, pass through ultrasound
Blending or quick stirring are uniformly dispersed with modified graphene, obtain high hydrophobic type antistatic composite coating.It is provided by the present invention
Composite coating takes into account hydrophobicity and the performance of antistatic, environmentally friendly without any fluorine-containing material, excellent durability, still
Reunite since graphene can generate itself, destroy its scattered uniformity, compactness, be applied to reunite during coating, apply
Stress concentration is generated inside film, mechanical performance, antiseptic property is caused to decline.Graphene is applied in anticorrosive paint at present has hardly possible
The layer of the defects of to disperse and graphene is easily overlapped the defects of aggregation again.
